Nikon already confrimed the rumors and announced the Nikkor 24-70mm F2.8 VR, 24mm F1.8 and 200-500 F5.6 FX lenses and B&H and other major reatilers are now taking pre-orders.

The Nikkor 24-70mm F2.8 VR will cost $2,396.95, about $500 more than the current lens and will provide 4-stops image stabilization and will share the trend for filter threads of 82mm.The Nikkor 24mm F1.8 will cost $747.The AF-S NIKKOR 200-500mm f/5.6E ED VR Lens will cost $1,397 with up to 4.5 shutter speed stops image stabilization

.

Now, let's wait for the response from Canon to these alternatives from Nikon. I personally believe that the current EF 24-70 f/2.8L II is one of the best lenses from Canon but, I will be very happy to get IS as well.

If Nikon can make a 200-500 f/5.6 and sell it for under 1400$, they why is it difficult for Canon to make 500mm f/5.6 prime lens for the same amount of money. So far for me the only reason why I am sticking with Canon is that MP-E 65, there are way by which I can do macro photography on a Nikon system as well. Someday if I start shooting birds then I am definitely switching over. Good by Canon.
